1) In "A Can of Happiness", Emi wins the special prize in a raffle, which turns out to be a can that supposedly holds happiness. There's even a weird little man who starts following her around, claiming he's the "god of the can" and trying to give her advice. But all she wants is for her relationship with her boyfriend to feel less like a one-sided crush. Will this can really help her be happy?

4) The proud tsundere Matsuda has been in love with happy-go-lucky Tsumura for ages, but she just can't tell him. Aggressiveness is her heart's only defence when she's near him - after all: "The Opposite of Love is Hate". Tsumura has never minded before, so what will happen when that changes?

5) Kawamura and Tanaka are going out now, although Kawamura thinks Tanaka is a bit scary, and it's actually Kondo-sempai who likes Tanaka. What went wrong? And why did Tanaka agree to go out with Kawamura in the first place? You'll find out in "I'll Always Be Here".
